This invention relates to an explosionmotor, in wh'ch all the cylinders are arhollow, the end to. the left in vided ranged in the same plane through the of the machine, with which shaft the cylinders'rotate.

The drawing shows an example of carrying out the invention.

Figure 1 shows the machine .seen from above, the cylinders being taken away. Fig. 2 is a lateral view of same, partially in section, Fig. 3 a view from the end,-partially in section, Fig. 4 the cylinders seen from above, and Fig. 5 a detail.

The shaft of the machine marked 1 is Fig. 2 forming the inlet-canal 2 for lighting or other explosive gas, while a pipe 3 is placed in the other end, through which pipe the combustion-products escape. The shaft 1 is integral with four hollow pistons 4r, arrange in pairs' at each side of the shaft, and all in the same plane. The pistons 4am in-. closed in cylinders 5 which are cast or formed in pairs which are so connected together by bolts 6 as to always preserve the same fixed correlation. Each cylinder 5 is integral with a shaft 7 and around each such shaft a wheel 8 is rotatably mounted upon suitable ball-bearings. At each side the periphery of wheels 8 frictionally engage the rim of a curved eccentric or cog-disklO, preferably of the shape shown in the drawing, and one at each side of the machine-frame. In Figs. 2 and 3 of the drawingthe upper cylinders are shown in their most advanced position,

while the piston IS in the bottom in the lowest cylinders which are in. their most retracted position. The cylinders are prowith external ribs of any desired form in order to increase the exposed surface, as the machine is air-coole The hollow pistons '4, bear outside tightening rings 11, and communicate directly with thesupply canal -2 in the shaft 1. In the interior of each piston is an outlet valve 12, for the products ofcombustion, and within each valve 12 there 'is an inlet-valve 13, for gas. Each HERMAN NIELSEN,

shaft op enin gs with pipe valve 12 moves in a tube 1 1 placed in the corresponding piston 4 and has, at its upper end, a valve-head 15, tightening against its tube. The valve 12 kept closed by a coiled spring 30 surrounding the tube 14 and pressing, at one end, against the head of this tube, while its other end presses against a pin 31, or the like, fitted through the valve12. In each tube 1a there is provided a circular groove 16, (see especially Fig. 3) communicating with a canal 17 (Fig. 2) formed lengthwise of a piston 4.- and communicating with the exhaust pipe 3 in the shaft 1; the two pistons shown at the extreme left hand side of the drawings communicate, however, through an intermediate pipe 18,

Figs. 1 and 5. In the interior of the valve 12 the valve 13 can slide, against the pull of-the coil spring 19, WhlCll holds the head or flange, 20, down against the valve 12, I prefer that each valve 12 shall be of the form shown in Fig. 3, that isprovided with 21, for the passage 0 the gas.

1 Each inlet-valve 13 is designed to be opened by the suction due to the partial vacuum which is produced when the cylinders leave tatable in bearings the pistons and the combustion-products are led out. The gas goes from the canal through the hollow valves '12 and, upon opening of valve 13, through the "openings 21 and to the cylinder 5. The outletvalves are moved by means of a cog-wheel 23 fixed to the machine-frame and having twice the number of teeth of the wheel 22 (Fig. 3). As the last named wheel is nonrotatably fixed to the machine-frame, the

wheel 23 must, when the machine is working, rotate around its shaft 24, which 1S'1'0- 25 fixed to the pistons l.

On the shaft or are arranged four cams 26, so as to'have each cam move a'corresponding rod 27, which can actuate one arm of an angle-lever, the other arm 28 of which can lift the corresponding valve 12, Fig. 5. For every two rotations of the shaft 1 the shaft 2 will rotate once, and consequently each of the valves 12 is opened once for every two rotations of the shaft 1, and, as regards the valves controlling two cylinders disposed opposite each other, at every rotation of the shaft 1.

One eccentric 1O isprovided with a terminal or bolt 32 to which-electric current is conducted, the-fother end of the bolt glidin g on a disk 33 which is placed on the shaft 1, and on which also glides one endofan arm 34, the other end of which is fixed to i the shaft 24 and partakes of the planetary movement of the latter; at the other end of the shaft 24 the current oppositely-disposed, hollow pistons, constituting continuations of and non-rotatably secured to said hollow shaft and containin valves for supplying charges of gas for ign1- smaller arm conductin it to an insution, and oppositely-disposed cylinders slidlated contact-piece 36 which is carried by ably fitting said pistons and connected in the wheel 23 and par-takes of the rotation permanent correlation. 7 thereof and will, upon each rotation, send t 3.
